HEM OR SEAM FOR SEWED ARTICLES.

Specification of Letters Patent.

. Patented Nov. 17, 1908.

Application filed July 19, 1905. Serial No. 270,328.

To all whom it may concern:

Be it known that I, JoHN G. Lnwrs, a-citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Hem or Seam for Sewed Articles, of which the fol lowing is such a full, clear, and exact description as will enable anyone skilled in' the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, forming part of this specification.

' My invention relates to a hem or seam for sewed articles," and more particularly to a hem or seam in which the sitches enter and emerge from the same side of the goods and form an over-seam. It has been usual heretofore to form such over-seam either by using a single thread and forming a chain stitch, or by using two threads and laterally vibrating the needle in order to form the over-seam.

The object of my invention is to produce a hem or. seam of the class above described in which the over-seam is formed by two threads and at the same time to so construct the hem or seam that will be unnecessary to accordance with my invention, Figure 1 is a 1 top plan view showing a form of hem or scam in which the edge of the goods 1s turned under and the stitches enter and emerge from the same side of the goods;

Fig. 2 is a view similar to Fig. 1, but showing a slight .modificationfand Figs. 3 and 4 are views illustrating the manner of forming the hems or seams shownin Figs. 1 and 2.

" Like marks of reference refer to similar parts in the several views of the drawings.

' figures this superimposed layer is formed by folding over 'a portion of the main layer. I The edge 12 is preferably also turned under.

as. best shown in Fig. 4. The stitches which secure the superimposed layer to the main layer are composed of a needle thread 14 and a bobbin thread 15. In order to formthe hem or scam the goods are bent around a guide or finger 16, as shown in Fig.4, and

the needle 17-is-passed through the goods in a direction diagonally across the direction of the lengthof the hem or seam. The arrows A in Figsil, 2 and 3 represent the direction of the feed of the goods. The needle 17 may either be inclined in a direction opposite to the feed, as illustrated by the line B in Fig. 3, or in the same direction, as shown by the line C in said figure. lVhen the needle is inclined in the opposite direction to the feed, the form of stitch shown in Fig. 1 will be produced, while if the needle is inclined in the direction shown by the line C, the form of stitch shown in Fig. 2 will be produced. In both of these forms of stitch it will be observed that the bobbin thread passes both through and around a loop of the needle thread at each stitch, the bobbin thread passing through theloop at a point 18 at one end of the stitch and around the stitch at a point 19 at the other end of the stitch. By the term ends of the stitch I mean the points atwhich the stitch enters and emerges from the goods. The only difference between the two forms of stitch is that in the form of stitch shown in Fig. 2, the bobbin thread is crossed after passing around the loop of the needle thread at 19. By the expression, passing around a loop -I mean that the thread referred to passes around both strands of the loop and not between the two strands.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is

1. A hem or seam for sewed articles comprising a main layer of textile or similar material and one or more superimposed layers secured to said main layer by a row of stitches entering and emerging at difierent points on the same side of the goods and composed of two threads, one thread passing around a loop of the other at one end of each stitch, and thence leading directly to and passing completely through said loop at the other end of the stitch, whereby a lock stitch is formed.

2. A hem or seam for sewed articles comprising a main layer of textile or similar material and one or more superimposed layers secured to said main layer by a row of stitches entering and 'emer 'ng at different points on the same side 0 the goods, and composed of a needle thread and a bobbin thread, said stitches extending across the length of the hem or seam and one thread passing around a loop of the other at one end of each stitch and thence leading directly to and passing completely through said loop at the other end of the stitch, whereby a lock stitch is formed.

3. A hem or seam for sewed articles comprising a main layer of textile or similar materlal and one or more superimposed layers secured to said main layer by a row of stitches entering and emerging at difierent points on the same side of the goods, and composed of aneedle thread and a bobbin thread, said stitches extending diagonally across the direction of the length of the hem or seam, one thread passing 'around a loop of the other at one end of each stitch and thence leading directly to and passing completely through said loop at the other end of the stitch, whereby a lock stitch is formed.

4. A hem or seam for sewed articles comprising a main layer of textile or similar materlal and one or more superimposed layers secured to said main layer by a row of stitches entering and emerging at different points on the same side of the goods and composed of a needle thread and a bobbin thread, said stitches extending across the directionof the length of the hem or seam, said threads forming an over-seam and the exposed portion of one of said threads lying in a substantially straight line in the direction of the length of the hem or seam, one

of said threads passing around a loop of the v other at one end of each stitch and thence leading directly to and passing completely through said loop at the other end of the stitch','whereby'a lock stitch is formed.

In testimony'whereof I have hereunto set my hand and afiixed myseal in the presence of the two subscribing witnesses. JOHN G. LEWIS.
